The Mediterranean Sea is considered a hotspot for climate change. The impacts of climate change are interacting with other environmental changes caused by human activities (e.g. overfishing, habitat loss and pollution). As a result, Mediterranean marine ecosystems and human livelihoods that rely on them are being affected. To contribute to reverse this severe degradation trend, MPA4Change focuses on enhancing Marine Protected Areas (MPAs) and restoration as nature-based solutions for climate change adaptation, aligned with the EU Biodiversity Strategy. The project aims to develop a sustainable and resilient Action Plan for Mediterranean and nearby Atlantic MPAs by strengthening their capacity to adapt to climate change, fostering policy dialogue at regional and European levels, and ensuring long-term implementation with expert guidance. Key actions include transferring ready-to-use toolkits, establishing a roster of experts, and integrating principles into public policies, positioning MPAs as central to climate adaptation efforts.
